They explain how to freeze food to reduce energy | Digital Trends Spanish

Freezing food is a convenient and practical way to extend its shelf life and preserve its flavor and properties. The problem is that it is not a sustainable way to manage what we eat, since it involves a high energy cost and a high emission of polluting gases into the atmosphere. The drawback is mainly due to the refrigeration devices used to store food. Now a group of researchers is proposing a new way of freezing food that could reduce energy consumption by as much as 6.5 billion kilowatt-hours a year. The resulting reduction in carbon emissions, of 4,590 million kg, is equivalent to taking close to one million vehicles off the road. According to the researchers, these savings could be achieved quickly and inexpensively, "without the need for significant changes to current frozen food...

New exoplanets will guide search for extraterrestrial life | Digital Trends Spanish

Researchers at the University of Cambridge, in England, discovered a new class of exoplanets that, according to them, would be excellent targets for the search for extraterrestrial life. These celestial bodies were called Hycean planets and are covered by oceans with atmospheres rich in hydrogen, which makes them so different from those on Earth. "These planets open a new avenue in our search for life elsewhere," says Nikku Madhusudhan, principal investigator at the Cambridge Institute of Astronomy. "It is exciting that habitable conditions can exist on planets so different from Earth," he adds. The researchers also indicate that this important finding "could mean that finding biosignatures of life outside our solar system in the next two to three years is a real possibility." According...

Meteorite provides important information about water on Mars | Digital Trends Spanish

An investigation carried out by the University of Tokyo revealed evidence of water from 4.4 billion years ago in a Martian meteorite discovered in the Sahara desert in 2011. Although it was already known that Mars harbored water about 3.7 billion years ago, with this new analysis of the NWA 7533 meteorite, the researchers estimate that the water was likely present a long time before. For researchers, this type of analysis helps to understand how Mars was formed and what the process of evolution of its crust and mantle was like. Also, the findings are in line with the hypotheses that hold that water could be one of the substances that occur naturally during the formation of planets. This look would distance itself from the theory that states that the meteorite, nicknamed "Black Beau...

NASA detects “elves” and “goblins” in the atmosphere of Jupiter | Digital Trends Spanish

New results from NASA's Juno mission suggest the presence of "goblins" or "elves" of light in Jupiter's upper atmosphere. They would not actually be mythological creatures, but rather Transient Light Events (TLE), unpredictable flashes of bright light that are extremely brief. According to the space agency itself, this would be the first time that these phenomena have been observed on another planet. These "goblins", also named after a mischievous character in English folklore, are transient light events caused by lightning discharges from electrical storms. On Earth, they occur up to 60 miles above intense and high thunderstorms and are capable of illuminating a vast region of the sky, but only last for a few milliseconds. The "elves", meanwhile, owe their name to the acronym Elve...
